[Leiomyosarcoma of the urinary bladder treated using laparoscopic cystectomy and bladder replacement by enterocystoplasty: about a case].

Our study aims to report a new case of leiomyosarcoma of the urinary bladder, a rare tumor, and to propose a new therapeutic approach, given the non-consensual nature of its treatment. A 31-year old patient, with no particular previous history, presented with total haematuria with clot formation. The clinical and paraclinical assessment showed a voluminous solid tumor mass occupying the apex of urinary bladder and extending to the right lateral wall, with infiltrating appearance, without lymph node involvement or invasion of local or distal organs. Surgical management was based on total laparoscopic cystectomy and bladder replacement by enterocystoplasty. The postoperative course was uneventful. Radiological examinations at 3, 6, 12 and 24 months showed no recurrence. Thus, adaptive surgery should be proposed on a case-by-case basis, to improve the quality of life of patients suffering from this condition.
